Yoshikage Kira doesn't summon Killer Queen to blow up Rubber Soul for "eating" his dog because Jotaro could be a potential witness. Also, the explosion would wreck the cable car.
The scene where DIO snaps at Steely Dan is not just a reenactment of the scene where Ceasar does the same to Wamuu, but an indicator of how DIO loved his mom. He saw J. Geil mourning over Enya and it reminded him of the abuse Dario put his mom through.
